Understanding Solar Eclipses

The video explains why solar eclipses appear to move from west to east, unlike the sun and moon, which rise in the east. This is due to the moon's shadow moving faster than the Earth's rotation. The video also discusses how changes in the Earth's size or the moon's distance could alter eclipse paths, and why some eclipses near the poles move differently due to the Earth's tilt.

What is unusual about the movement of solar eclipses compared to the sun and moon?

• They move from east to west.

• They move from west to east.

• They do not move at all.

• They move in a circular path.

What determines the path of the moon through the sky?

• The rotational speed of the Earth.

• The position of the sun.

• The line of sight from the Earth's surface.

• The speed of the moon's shadow.

Why do eclipses appear to move from west to east?

• The moon's shadow travels faster than the Earth's rotation.

• The Earth's rotation is faster than the moon's orbit.

• The sun's position changes rapidly.

• The stars influence the eclipse path.

What is the speed of the moon's shadow as it travels across the Earth?

• 2000 miles per hour

• 4000 miles per hour

• 3000 miles per hour

• 1000 miles per hour

How long does it take for the moon's shadow to cross the Earth?

• 1 hour

• 6 hours

• 12 hours

• 3 and a half hours

What factor allows the moon to travel faster than the Earth's rotation?

• The Earth's smaller size.

• The moon's proximity to the Earth.

• The moon's larger orbit.

• The sun's gravitational pull.

What would happen if the Earth were twice as big?

• Eclipses would move from east to west.

• The direction of moonrise would change.

• The moon would orbit faster.

• The length of a day would change.

What would happen if the moon were half as far away from the Earth?

• Eclipses might move from east to west.

• The Earth's rotation would slow down.

• The length of a month would change.

• The direction of moonrise would change.

Why do some eclipses near the poles move westward?

• The moon's orbit is irregular.

• The Earth's rotation speed varies.

• The Earth's axis of rotation is tilted.

• The sun's position is unstable.

How can you visualize eclipse paths using Google Earth?

• By drawing diagonal lines.

• By drawing circular paths.

• By drawing west to east arrows.

• By drawing vertical lines.
